New article Offline Charts in the New MQL4 has been published:
Updated MQL4 has the new format for storing historical data and provides
the appropriate MqlRates structure for convenient storage of Time,
Open, Low, High, Close and Volume values. For many years, traders have
developed their MQL4 applications that collect and store their data in
HST files for generating offline charts. We can assure you that all
previously compiled EX4 files will work in the new MetaTrader 4 terminal
the same way as before.
Interesting... I had some problems with offline charts some days ago, it was fixed thanks to a help of a friend of here..
I will read carefully this article, maybe I was doing something wrong, or something in my indicator..
